(Please answer it correctly please please show work )Thalia tosses a fair number cube with faces numbered 1 to 6. Which is a rea
anastassius [24]

Answer:40

Step-by-step explanation:

On a fair die, each face has a 1/6 chance of landing on each toss.

5 and 6 are the only faces greater than 4, therefore there is a 1/6 + 1/6 = 2/6 chance of the die landing on a number greater than 4 for each toss.

Multiply the probability by the total number of tosses to get the number of tosses that are greater than 4.

120 * (2/6) = 240/6 = 40

Approximately 40 tosses will land on a number greater than 4.

A discounted amusement park ticket costs $12.95 less than the original price (p). Write and solve an equation to find the origin
Elena-2011 [213]
P = the original price of the ticket.

Let x =  the discounted price.
The discounted price IS $12.95 less than the original price. Therefore
x = p - 12.95

Add 12.95 to each side.
p = x + 12.95

Answer:
The equation is
p = x + 12.95
where
p = original price
x = discounted price
